0800 013 6673 Neutral Who called me from this phone number?

Persistent calls from 08000136673 registered on my phone which is bordering on harassment as I refuse to answer.

bloody fuckers ringing up every day, don't even answer anymore. Last number that did this I pretended to be a sex-line worker so they'd hang up, needless to say they didn't call back

I don't like these people calling me from this number, they smell. I'm a lonely person with no mates, and that's the way I want it to remain. Please don't call me anymore you smelly smelly people

I gave all my bank details tothis person he said he was from O2

I have just received a call from 0800 013 6673, the lady who called identified herself as Debbie and she was calling from O2. I immediatley stated that I was not interested in what they were selling as in my opinion if I want something I will go out and buy it rather than being pestered into buying something. "Debbie" claimed that she was calling about my tariff. At this point I ended that call. Not to be trusted as I have no tariffs as not on contract

Got a call from this number yesterday and today but didnt answer it

This number keeps calling me when I am at work. I am not answering it and would like them to stop!

Constant telephone calls. Nuisance!!

Had 3 calls from these clowns today. Am sick to death of them. O2 sort this out or you will be losing a lot a customers, I for one, am thinking of taking my custom elsewhere just to get rid of these harassing phone calls...

I have been getting up to 15 calls a week from this number, I have answered once just to see who it was and found out it was an O2 number, not sure what they where ringing for as I hung up straight away, but they are becoming real pests! I have blocked previous numbers from O2 cold calling me, but some how they always seem to find a different way to ring me. Best advice would be to block the number, they don't get the hint!!!

This number called twice today. I wish to report it. If as the other people have suggested, it is my mobile phone provider, I know where they are & if I require assistance, I will call them.

Just started getting calls from this number (29th May onwards) - once or twice a day. Very annoying!

This number rings me all the time! They claim to be from o2 but I am too scared to talk to them in case they hack into my phone or something. I wish they would leave me alone, I don't know why they keep phoning me because if I had a problem I would go into an o2 store. So annoying!

Who the fuck are these slags they have rang me 8 times today whoever they are they are getting blocked they are becoming an Annoyance.

The official and correct numbers for o2 sales are: normal sales: 08442020202 Business sales: 08000280202 LBM: 08000890118 O2 does work with LBM but not on 08000136673. We are not aware of this number and would advise not to provide any details. they should not be asking for bank details as they should already have them and they are not allowed to ask for them if they call you.
